Peltier question
Hi I have a question about using a peltier not in the traditional way for PC’s I know they are used in conjunction with water cooling, but what I wish to do is use the peltier as a 2ndary cooling devise primarily the cooling of the water, using a heatsink/heatsink heatpipe and a water block, the cold side would cool the water block as the water is passing through in the cooling system.
Why do this? Well my hopes are of dropping the temperature lower then ambient, this is for attempting to build a carPC for extreme summer heat, temperatures for example in Arizona during the summer can reach well over 150F in the car, that is not good for PC components and even water cooling will not be able to function well, my goal is to try and drop the water temperatures and allowing the radiator to dissipate the heat slowly as the car temperatures normalize after the passenger enters and drives.
I have read the article and understand the inefficiencies of the peltier, but those are applying were the peltier is responsible for removing the whole cpu temperature and the heatsink having to cope with the peltiers added heat as well, in my case water keeps its temperatures a bit stable it will take a bit to cool it but take longer for the temperatures to equalize
I also understand that the peltier would be effected by the ambient temperature, I do not wish to get a lot of efficiency as this is to be a 2ndary cooling way for short durations, but enough to be able to have lower then ambient temperatures on the CPU area
